Price in title inclusive of GST.
The much hyped Phillips SHP9500 for about half price at AliExpress: these are open-backed monitor headphones that are really good for listening at home. Head-fi loves them. This isn't the cheapest price they were $58 once in 2015) but they've been discontinued resulting in high prices, so this is a good opportunity to grab one before they disappear of the face of the earth. I'd get a pair myself if I didn't have two(!) pairs of HD681 EVOs.
While these headphones have been at lower prices before, they no longer are offered at discount. It is actually surprising to see this, because since they have been discontinued their prices have went through the roof.
There are a lot of reviews for them, none give them a bad review, many praise their qualities, some even compare them to much higher priced headphones.
Here is my favourite review of these headphones: https://youtu.be/aipXii-qWiQ
Although I have not tested or used them myself, honestly all I have heard is good things about them.
If you don't mind open-headphones (that leak sound out), they are great for gaming. Probably the best at this price range for open-headphones actually. Comfort is great (they are massive too), the sound stage is wide, and the imaging is good.
